Colloidal synthesis of uniform-sized molybdenum disulfide nanosheets for wafer-scale flexible nonvolatile memory

Abstract

Large-scale colloidal synthesis and integration of uniform-sized molybdenum disulfi de (MoS2) nanosheets for a fl exible resistive random access memory (RRAM) array are presented. RRAM using MoS2 nano sheets shows a approximate to 10 000 times higher on/off ratio than that based on exfoliated MoS2. The good uniformity of the MoS2 nanosheets allows wafer-scale system integration of the RRAM array with pressure sensors and quantum-dot light-emitting diodes.
